iAccess Keyboard help

Hey guys,
I have a question which I know will be answered here so let me get out with it.

The themed keyboards we have been waiting for from cydia didn't come out, why? And how is it that iAccess is able to make a themed keyboard to work in some areas, but not all of them? In some apps or in cydia or in notes the keyboard results back to the original, why?

for me notes keyboard are themed. i think in cydia they did that because in Iacces keyboards, there isnt a search or enter button, it says "your trial is up" when you try to press it. its just easier to have the keyboard normal when browsing safari or cydia, so you can press enter.
